Snaz Posted August 12, 2008 Share Posted August 12, 2008 New Walmart opened up(HUGE!) and they have a brand spanking new Culligan water dispenser that the brochere says provides very pure water. Sediment -> RO -> UV. The water in my city is already really good, does anyone have experience with the Culligan machines? Suitable for a reef? DI water from the drugstore is starting to get expensive! I was thinking of taking a sample for testing, basically what I am interested in is TDS < 50 and Cu =0 correct? Sorry for the newb questions. Thank you. Snaz. Link to comment
Turkey Baster Posted August 12, 2008 Share Posted August 12, 2008 My RO/DI water has a TDS reading of 1. I'm not sure that < 50 is acceptable in a reef. Link to comment
CorvetteJoe Posted August 14, 2008 Share Posted August 14, 2008 Just did some research on this... Culligan machine just looks like an expensive RO vending machine, so it SHOULD produce 0TDS or close enough to it. Distilled = 0 TDS RO/DI = 0TDS Distilled = $.69/gal at Target Distilled is supposedly 1 step better than RO/DI... but both produce 0 TDS. Link to comment
masterbuilder Posted August 14, 2008 Share Posted August 14, 2008 New Walmart opened up(HUGE!) and they have a brand spanking new Culligan water dispenser that the brochere says provides very pure water. Might be OK for now, while its brand new.... but...when do you think they will get around to changing the filter? At 5 TDS, 50TDS or 500TDS? Link to comment
chuckfullservice Posted August 14, 2008 Share Posted August 14, 2008 I took my taps water to my LFS and it tested 10ppm TDS. I use it in my tank and everything is doing great! Link to comment
